AUG. Armee Universal Gewehr. 5.56x45mm, select fire, assault rifle manufactured by Steyr-Mannlicher of Austria. Used by the Austrian military as the Stg.77 (Sturmgewehr, year 1977), used by the Australian Defense Forces as the F88 AUSTEYRm and used by the Irish Defense Forces, among other numerous militaries.

It is a gas-piston operated rifle, using the revolutionary bullpup design (magazine and action located behind the trigger), and allows M16A2 length barrel, in an overall package the size of an M4A1 carbine. The stock is made of high-strength polymer, and has endured being run over by a Unimog over 30 times. The reciever is made of aircraft-grade aluminum casting, and either houses a 1.5x optic, or an optic rail. Barrels and receivers are fully interchangeable. Barrels include a 16" carbine, 20" rifle, and 24" HBAR (Heavy Barreled Assault Rifle), with a bipod. The magazines are made of translucent polymer, and can hold either 30 or 42 rounds.

Select fire is accomplished by a "pull through" trigger system: half-pull is semi-automatic, complete pull is full-automatic. There is a distinct stopping point between the pulls so that accidental discharge of full-automatic is rare.

Variants include:

AUG A1-receiver housing has either a 1.5x optic or rail mount
AUG A2-receiver housing has a removeable 1.5x optic or rail mount

AUG A3-essentially an AUG A2 with a RIS system.
The Steyr AUG was banned from the United States because it "looks menacing" and has fewer than 7 American made parts. In other words, the AUG was banned for bullshit reasons.

Said when something is augs. Sometimes the letter g is added to make it sound more gangsta, such as "augs g".
